Utility
Preparation of isocyanatosilanes
23 May 23
There is provided herein a method and an apparatus for producing an isocyanatoorganosilane which method includes feeding a carbamatoorganosilane to a cracking device where it is thermally dissociated into a reaction product mixture comprising isocyanatoorganosilane, alcohol, and heavies, followed by separating the mixture in a distillation column of two parts and collecting the isocyanatoorganosilane from the distillation column via a side stream having a predetermined location between the top and bottom parts of the column; and wherein the distillation column is configured to have a ratio of the length of the bottom part of the distillation column to the length of the top part of the distillation column which is effective to provide a side stream having a high purity and high weight percent of isocyanatoorganosilane.
